We found this infographic from Talentful quite interesting. These 15 cases of employee headhunting and company switching were used to find out which tech giants poaches the most employees.
The details were conferred mainly using Linkedin data. The total number of current employees for each company was taken from LinkedIn. After this, they found out the past company details of these employees also from LinkedIn.
